First Time learning about the Tyranid Lore | Warhammer 40k Reaction

The Tyranids are fascinating because of how out of context they are compared to the rest of the setting. They don't care about the War in Heaven, the Great Crusade, the Horus Heresy, Abaddon's tantrums across the galaxy, the political situation of the Tau, the Fall of the Eldar or the thirsting of laughing gods. They're just here to eat. While this can be seen as them being superfluous (while you can extract them from the setting while changing very little aside from the details, you could more or less say the same about all non-Eldar xenos races), it essentially means that they are an existential threat to everything in the galaxy, from humanity to the Eldar, greenskins and even the League of Votann. They don't care about the games of the gods, the Greater Good or the Webway Project: they're here to eat. And they're HUNGRY. And they will eat everything they can, with the only things left are the unchanging metallic frames of the Necrons. They also have some of the strongest visual cohesion in all of 40k. Sure the Ultramarines are all blue but they have weapons, gear and vehicles that break the general silhouette. Orks are a visual chaos with a same color scheme, while Knights have similar frames but with wildly differently colored heraldry. Chaos Marines have a variety of units, and while a mono-god Daemons army has strong color cohesion they are not that viable. By contrast, all Tyranids except for the mines, their drop pod and the fortification have the same basic form: a boney torso with exposed but hardened ribs, six limbs ending in similarly looking claws/blades/talons, firearms that resemble grotesquely warped creatures in their own right, or powerful legs ending often in hooves; a head with chitin that extends to the creature's torso that on larger creatures have biological chimneys to regulate the creature's temperature; and a tail that can have its own row of chitin on it and on large creatures ends in a weapon. All Tyranids, ranging from the basic Gaunts to the Warriors, the Carnifexes, Exocrines, Mawlocs and even the new Norn creatures: from Ripper to the mighty Swarmlord, they all have look like this. Then there's the coloring: in a cohesive army they all have the same colors on the same places. Sure some have more chitin, others have more skin, some have exposed brains with others having wings, but the coloring and the places of the colors are cohesive in ways that no other army can claim they are. And that's why I've been playing them for the last 20 years.
